A head gasket assembly for closely adjacent cylinder bores and method of making the assembly. In the zone of adjacency of the combustion openings in the gasket assembly, part of the gasket body material is absent. Adjacent armoring is joined to form a bridge at the zone of adjacency. The armoring has wires which are substantially greater in thickness than the gasket body material. When the gasket assembly is pre-compressed and compressed in use, the wires in the zone of adjacency are deformed into sealing engagement with each other.

Head gasket assembly for closely adjacent cylinder bores and method of

A method of making a composite gasket. A composite gasket is formed from an annular coiled strip of heat-resistant core material having a metallic tanged core and a facing layer, as of a mica-based material, integrated with the strip. The coil is placed in a first die and axially compressed under a relatively low pressure into a preform having a plurality of crevices in its face. The preform and a temperature-resistant sealing material, such as expanded graphite, are placed in a second die and the graphite and preform are axially compressed under high pressure to integrate the sealing material with the preform and to mechanically interlock the sealing material with crevices in the surface of the core material. The preform and sealing material are substantially deformed during the second axial compression to provide an improved composite gasket.
